Fi 4 a side elevation of a slightly modified 'form of liner partly broken aw'ayand in ksection; upon disposition of a member or element F ig. 5 is top'vieW thereof;

Fig. 6 is a side view of a tool or wrench employed to permanentlyposition in its support the liner shown at Figs. l to 3;

Fig-.f7 is a sectionalviewthereof on the line 7-7 of Fig. 6;

Fig. 8 is a side view of a tool yor Wrench employed to insert and' remove the liner shown at Figs. l 4and 5 into and from its support, and

Fig. 9 is a sectional view thereof on the line 9-9 of Fig. 8.

In said drawings the support or tie 10 has embedded or secured'therein a socket or sleeve' l1 provided with the exteriorly arranged projecting threads 12 which serve to permit ready disposition ot the sleeve l1 Within the support l0 and to provide anchoring or gripping lel-.enfients biting into the yieldable material of the support to firmly hold and retain the liner therein.

The interior` surface of the liner l1 is provided with threadsl (shown as spiral grooves) to permit the fastening member 14 to be screwed yinto the same. The member 1a is illustrated as one form of railway screw spike comprising a threaded shank portion 15 ofrsubstantially uniform cross section, a tapered intermediate portion 16,` a head 17 adapted to engage the rail 18 to retain the sainev against the support 10 and a polygonal end 19 adapted to be engaged by a wrench to screw orturn down said spike 14 into the liner or sleeve 11. The sleeve or liner embodying my invention may be designed to receive fastening members of different types or shapes.

The upper end 2O ofthe sleeve 11 is enlarged or diverges to conform with. the tapered portion 16 of the spike to limit the downward movement thereof into the liner 11. The lower threaded portion 21 of the sleeve 11 is of a substantially uniform cross section, and'has its interior portion tapered slightly towards its lower end to provide a bore therein of a diameter slightly less than the diameter of the shank 15 or the member 14 for a purpose hereinafter more fully described.

The sleeve 11 is composed of two separate longitudinal parts 'or sections 22 and 23 engaging each other along the longitudinal edges 211,'and provided with intcrengaging means 25 atopposite sides thereof to prevent relative'longitudinal movement of the lparts when assembled. rl`he means 25 consists of tongues projecting from certain edges ofthe sections and extending into cooperating recesses at the opposing edges of the sections.

The enlarged portion 20 of the sleeve 11 has an interior tool receiving recess or socket l-26 therein forming an abutment or ledge 27 adapted to be engaged by the tool.

ln the form of sleeve illustrated at Figs. 1 to 8 the recess 26 is cylindrical in cross section, and in the form illustrated'at Figs. 4t and 5 the recess26a is polygonal in cross section. Y

The first mentioned form of sleeve is adapted to be permanently or non-removably secured within the support 10 by means of the'v tool or wrench 28 illustrated at Figs. 6 and 7. The second mentioned form of sleeve lwhich is removable is secured in position and removed by means of the tool or wrench 29 illustrated in Figs. 8 and 9.

The wrench 28 comprises a threaded shank 30 of uniform diameter adapted to fit into the interiorly threaded portion of the sleeve 11, and an enlarged cylindrical portion or shoulder 31 adapted to fit into the cylindrical recess 26 and engage the abutment 27. A crank 32 is provided for rotating the tool.

The wrench 29 has a reduced unthreaded shank 30a of uniform diameter adapted to fit into the interiorly threaded portion of the sleeve 11, and a polygonal portion or shoulder 315' conforming in shape with that of the recess 26 and adaptedto lit therein. The wrench 29 is likewise provided with a crank 32, y

To position the sleeve, a hole is iirst bored in the support 10 and, in some cases, as when the wood or material is unusually hard, a thread maybe formed therein. To insert the first form of sleeve into the hole the two sections 22 and 23 thereof are placed on the shank of the tool 28 with the threads thereof meshing with' the threads 13 of the liner, the several means 25 interengaging. The sleeve 11 is then screwed into.` the hole by rotating handle or Acrank 32. The Asleeve 11, after any relative movement of the wrench 2S therein ceases, is forced into the hole'and then retained securely in position therein. The wrench 28 is removed by rotating the same lin' the reverse direction.

rllhe removable type of sleeve 11, Figs. l and v5, is, in like manner, secured within the hole of the' support 10 by fitting the polyg onal shoulder 31 of the tool 29 into the correspondingly shaped recess 26a and rotating the tool. The recess 26a and tool 29, owing to the polygonal Vcontours thereof, are `adapted to permit of the removal of the sleeve when desired. u

The threaded spike 14 is screwed into the sleeve -11 by the rotation of a suitable tool applied to the polygonal end 19 thereof. rlhe 'shank 15 of the spike by its engagement with the lower portions of the sections 22 and 23 serves to spread or expand the same and forcethe exterior threads 12 of the sleeve 11 iirmlyinto gripping engagement with the material of the support 10, and hold the spike firmly in position within the sleeve. My invention is especially valuable on railway lines having heavy traffic and sharp curves, requiring 'frequent-.replacement or renewal of the rails. When my invention is utilized the screw spikes canberepeatedly removed and replaced without injuring the fibre of the wood, and thus avoiding the weaking or destruction of the support by repeatedly making holes therein. The sleeve lembodying my said invention .also aoi'ds a firmer hold for the spike than when the same is directly embedded in the wood.

Having thus described my said invention, what I claim and desire to secure by Letters Patent is Q (il 1. A device of the'character described comprising an expansible, tubular socket member having correspondingly inclined threads upon the inner and outer surfaces thereof; said socket'member having a tool receiving recess therein at an end to permit of the rotation thereof to-seoure the same within a supporttherefor, substantially as specified. l

2. A device of the character described comprisingl an exteriorly threaded, tubular socket member consisting of a plurality of separate longitudinal sections having a tool receiving recess at one end formed partly on each of said sections, substantially as specified.

3. A device of thev character described comprising an interiorly and exteriorly threaded, tubular socket member having an enlarged recess therein at one end, and an interior portion tapering towards the opposite end; said socket member including separate longitudinal sections, and interengaging means to prevent relative longitudinal movement of said sections When assembled; said sections being adapted to receive a tool therebetween and within said recessed p0rtion to permit of the rotation o t' said socket member to secure the same Within a support therefor and being adapted to receive a threaded member cooperating with said tapered port-ion to expand said sections into engagement with said support, substantially as specified.

4:; A device of the character described comprising a substantially cylindrical socket member including separate longitudinal seotions, and interengaging means to prevent relative longitudinal movement of said sece tions, and correspondingly inclined threads of uniform depth disposed uniformly substantially throughout the entire length of the inner and outer surfaces of said socket member, said socket member being provided at the upper end thereof With a recess for receiving` a tool to permit of the rotation of said socket member to secure the same Within a support, and adapted to receive a threaded member for expanding said sections into engagement with said support and to secure an object in position upon said support, substantially as specilied.

5. A device of the character described comprising' an exteriorly and interiorly threaded, tubular socket member composed of a plurality of separate longitudinal sections having interengaging portions to prevent relative movementthereof; said socket member having a tool receiving recess at one end, and an interior Wall portion tapering towards the opposite end, substantially as specified.

Signed at the city of New York, borough of Manhattan, in the countv and State of `New York, this 21st day of March, one

thousand nine hundred and twenty-four.
